how do i solve this?

Answer:($7.76/4)x 13

Step-by-step explanation: There is no way to start from the price of 4 glue sticks. So, you have to find the unit rate. The unit rate is the cost of 1 of the items. For example, if 8 apples was $5.65, you have to find out what 1 apple cost so you can buy as many apples you want, not just 8. After finding the unit rate, multiply the unit rate by 13. Back to the apple example, if I did not want 8 apples but 15, and I want to know what the price is before I go up to the counter to buy it, I would multiply the unit rate by how much I want.

Also, the answer to ($7.76/4)x 13 is $25.22. The unit rate was $1.94.

Answer: 10.0

Step-by-step explanation: In this problem, we are asked to round 10.034 to the nearest tenth. It's important to understand that the tenths place is 1 place to the right of the decimal point. So the digit in the rounding place is 0.

Next, look at the digit to the right of the rounding place which in this case is 3. Since the digit to the right of the rounding place, 3, is less than 5, we round down.

This means that the digit in the rounding place, 0, stays the same and we change all digits to the right of the rounding place to 0.

So 10.034 rounded to the nearest tenth is 10.000 or just 10.0 since we can drop zeroes at the end of a decimal.

The rate at which the area of the triangle changes when the height is 22 cm and the base is 10 cm is 14 cm²/min.

Using the formula for a triangle's area, A = (1/2) × base × height, we can determine rate of the triangle's area changes.

We can describe the rate of change of the base as db/dt = -1 cm/min (negative because it is shrinking) given that the base is shrinking at a rate of 1 cm/min.

The height is increasing at a rate of 5 cm/min, so the rate of change of the height can be expressed as dh/dt = 5 cm/min.

We must determine dA/dt for h = 22 cm and b = 10 cm in order to determine the rate at which the triangle's area changes at these two points.

We can start by differentiating the area formula with respect to time (t):

dA/dt = (1/2) × (db/dt × h + b × dh/dt)

Substituting the given values:

dA/dt = (1/2) × (-1 cm/min × 22 cm + 10 cm × 5 cm/min)

Simplifying:

dA/dt = (1/2) × (-22 cm/min + 50 cm/min)

= (1/2) × 28 cm/min

= 14 cm/min

Therefore, the rate at which the area of the triangle changes when the height is 22 cm and the base is 10 cm is 14 cm/min.

The rate at which the area of the triangle changes is 2 cm²/min. This is found by applying the chain rule of differentiation to the triangle area formula, substituting the given values and rates, and simplifying.

The subject of this question is rate of change in context of the Triangle Area Formula: 1/2 * base * height. Given that the base is shrinking at a rate of 1cm per minute (1 cm/min) and the height is increasing at a rate of 5 cm/min, we can express this rate of change in the formula. A negative sign is used for the base because the base length is decreasing.

To find the rate of change in the area, use the chain rule of differentiation, leading to the formula (-1/2 * height * db/dt) + (1/2 * base * dh/dt). When the height is 22 cm and the base is 10 cm, substituting these values along with the rates at which the base and height are changing, the formula becomes (-1/2 * 22cm * 1 cm/min) + (1/2 * 10cm * 5 cm/min). Simplify to find that the area of the triangle is changing at 2 cm²/min.

Answer:

36 ounces

Step-by-step explanation:

The common relationship between 24 ounces and 8 ounces is that 8 times x= 24.

24 divided by 8 is 3. Applying this same technique, we can figure out that 12 times 3 is 36.

Answer: 36 oz of oil

Ratio of oil to vinegar: 3:1

Step-by-step Explanation:

1)  The oil to vinegar ratio of the recipe is calculated my dividing the amount of oil (oz) by the amount of vinegar (oz)

         24 ÷ 8 = 3

      This 3 means you have 3 parts oil for every 1 part vinegar, ratio being: [tex]\frac{3}{1}[/tex]

2)

[tex]\frac{3}{1}[/tex] ⇒ [tex]\frac{?}{12}[/tex]

             To get the denominator from 1 to 12 you must multiply by 12.

            You must do the same to the numerator (top of fraction) meaning you mus multiply 3 (The ratio's nominator) by 12.

                     3 × 12 = 36

3)

The answer is 36 oz of oil

Answer Check:

To Check answer you can do 36 ÷ 12

And if it equals 3 than we know that the ounces of oil (36) over the ounces of vinegar (12) give us a ratio of 3:1  Which is the same ratio as used in the recipe. (24:8)

Step-by-step explanation:

A man gave an amount of money to his three sons Yao, Esi and Ampa in the ratio of  their years

We need to find the amount given to them

Let us use the ratio method to solve the problem

∵ Yao is 15 years old

∵ Esi is 10 years old

∵ Ampa is 5 years old

∴ The ratio between them is

→  Yao    :    Esi    :    Ampa

→  15       :    10     :    5

Simplify the terms of the ratio by divide each term by 5

∴ The ratio between their ages in the simplest form is

→  Yao    :    Esi    :    Ampa

→  3         :    2      :    1

∵ Esi had GHS100.00

→  Yao    :    Esi    :    Ampa    :   Total

→  3         :    2      :    1             :   6 ( 3 + 2 + 1 = 6)

→             :  100     :                  :    x

Use the cross multiplication to find x

∵ 2(x) = 100(6)

∴ 2x = 600

- Divide both sides by 2

∴ x = 300

So first we have to know what (fog)(x) means. Whenever we have the notation (fog)(x) or (gof)(x) or whatever variables (hof)(c) it means that we put the function closest to the x in the other function.

Basically for (fog)(x) this means put g(x) in f(x)

For (hof)(c) this means put f(c) in h(c)

For (gof)(x) this means put f(x) in g(x)

So now we can proceed with the problem.

f(x) = x^2 - 2 (I assume you wrote x squared) and g(x) = x - 3. Find (fog)(x)

So we are going to put g(x) in f(x). So wherever there is an x in f(x) we are gonna replace that with x -3:

f(g(x)) = (x-3)^2 - 2

If we want we can foil this out:

(x-3)(x-3) - 2

x^2 - 6x + 9 -2

or x^2 - 6x + 7

So: (fog)(x) = x^2 - 6x + 7

Answer:22%

Step-by-step explanation:

You paid approximately 27.12% gratuity on a $59 bill by leaving a $16 tip on a $75 payment.

To find out the percentage gratuity paid, you can first calculate the gratuity amount by subtracting the bill amount from the total paid:

Gratuity = Total paid - Bill amount

Gratuity = $75 - $59

Gratuity = $16

Now, to find the percentage gratuity, divide the gratuity amount by the bill amount and then multiply by 100:

Percentage Gratuity = (Gratuity / Bill amount) * 100

Percentage Gratuity = ($16 / $59) * 100

Percentage Gratuity ≈ 27.12%

So, you paid approximately a 27.12% gratuity.

There is no specific requirement in the question, but I'm assuming you need to compute the time needed for Alexis reach 1,000,000 Instagram followers

Answer:

[tex]t= 462.82\ days[/tex]

Step-by-step explanation:

Exponential Growth

When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is

[tex]\displaystyle f(x) = f_o(1 + r)^t[/tex]

Where [tex]f_o[/tex] is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)

The initial value is 100 Instant followers, thus:

[tex]\displaystyle f(x) = 100(1.01)^t[/tex]

We need to know when the number of followers will reach 1,000,000. Setting up the equation

[tex]\displaystyle 100(1.01)^t=1,000,000[/tex]

Simplifying by 100

[tex]\displaystyle (1.01)^t=10,000[/tex]

Taking logarithms

[tex]\displaystyle t\ log(1.01)=log\ 10,000[/tex]

[tex]\displaystyle t\ log(1.01)=4[/tex]

Solving for t

[tex]\displaystyle t=\frac{4}{log(1.01)}=925.63[/tex] periods of 12 hrs

[tex]t= 462.82\ days[/tex]

Alexis will reach 1,000,000 followers in approximately 462.82 days.

To calculate how long it will take Alexis to reach 1,000,000 followers, we can use the following equation:

f(t) = f(1+r)^t

We know that Alexis currently has 100 followers (f=100), and she wants to reach 1,000,000 followers (f=1,000,000). We also know that her follower growth rate is 1% every 12 hours (r=0.01).

To solve for the time (t) it will take Alexis to reach 1,000,000 followers, we can use the following steps:

Divide both sides of the equation by f(1+r):

f(t)/f(1+r) = (1+r)^t

Take the natural logarithm of both sides of the equation:

ln(f(t)/f(1+r)) = t * ln(1+r)

Divide both sides of the equation by ln(1+r):

t = ln(f(t)/f(1+r)) / ln(1+r)

Substitute the known values into the equation:

t = ln(1,000,000/100) / ln(1+0.01)

Solve for t:

t = 462.82 days

Therefore, it will take Alexis approximately 462.82 days to reach 1,000,000 followers.
